If user interface 230(is implemented) can communicate by letter with treatment circuit 210 offers user to receive the indication of users input and/or that can listen, appreciiable, machinery or other outputs at user interface 230 places.Therefore, user interface 230 can comprise, for example telltale (for example, touch-screen), one or more button or button and/or other I/O mechanisms.In some embodiments, user interface 230 for example can be arranged on mud guard, in the part of (, being positioned to contiguous seat 20), bearing circle 36, in the part of the steering pedestal 38 or another position of battery powered riding lawn Hospital trolley for nursing 10.
In the exemplary embodiment, memory device 214 can comprise one or more non-provisional storage equipments, for example, and such as fixing or detouchable volatibility and/or nonvolatile memory.According to an illustrative embodiment of the invention, memory device 214 can be configured to storage for making driving governor 150 can carry out the information of various functions, data, application program, instruction etc.For example, memory device 214 can be configured to the input data of buffering for processing by treater 212.Additionally or alternatively, memory device 214 can be configured to the instruction of storage for being carried out by treater 212.As another replaceable scheme, memory device 114 can comprise can be in response to the input from sensor network one or more data banks of store various kinds of data group.In the content of memory device 214, can store the application program carried out by treater 212 relevant with each corresponding application program functional to realize.In some cases, as hereinafter described in more detail, application program can comprise the controlling application program of utilizing the one or more and/or electric drive motor 62 in supplemental characteristic control blade motor 110.
Treater 212 can many different modes embody.For example, treater 212 can be presented as various processing equipment, such as microprocessor or other processing elements, coprocessor, controller or comprise integrated circuit (for example,, such as ASIC(special IC), FPGA(field programmable gate array) etc.) and various other computing equipments or treatment facility in one or more.In the exemplary embodiment, treater 212 can be configured to carry out be stored in memory device 214 or otherwise for the addressable instruction of treater 212.Therefore, no matter be to be configured by hardware or by the combination of hardware and software, treater 212 can represent such entity (for example, being presented as physically circuit-with the form for the treatment of circuit 210), this entity executable operations according to the embodiment of the present invention in the time correspondingly configuring.Therefore, for example, in the time that treater 212 is embodied as ASIC, FPGA etc., treater 212 can be the hardware of the special configuration for carrying out operation described herein.Alternatively, as another example, in the time that treater 212 is embodied as the actr of software instruction, instruction can be configured to treater 212 carry out operation described herein especially.
In the exemplary embodiment, treater 212(or treatment circuit 210) can be embodied as driving governor 150, comprise this driving governor or additionally control this driving governor.Therefore, in some embodiments, treater 212(or treatment circuit 210) can be understood as by response to correspondingly constructing treater 212(or treatment circuit 210) instruction or the execution of algorithm to guide driving governor 150 to bear functional accordingly, to cause the described each operation relevant with driving governor 150.As an example, driving governor 150 can be configured to control the actuating speed of battery powered riding lawn Hospital trolley for nursing 10 as described herein.
According to controlling application program and/or the instruction of the corresponding control behavior that limits parameter input and take for special parameter incoming signal or its combination, driving governor 150 can provide control signal to one in electric drive motor 62 and blade motor 110 or both.In the exemplary embodiment, driving governor 150 can be configured to receive the indication of total current, and indication based on received provides control signal to electric drive motor 62.Therefore, for example, driving governor 150 can comprise the detection that limits the measurement range of total current and/or the parameter list of value and measure in response to the total current by sensor network sensing in limited range or at limited value place and the corresponding control function of taking.The scope limiting in parameter list and/or value can be corresponding to the states for best or desired cutting property is provided and/or for the state in life-span of maximum battery power 74.
In some embodiments, control function can comprise provides speed control signal to electric drive motor 62.Speed control signal can comprise the instruction that impels electric drive motor 62 to slow down in response to the total current receiving exceedes the indication of threshold value.In this respect, in some embodiments, blade motor 110 can for example, operate with the speed (, maximum speed, actv. speed etc.) of fixing by corresponding blade motor controller 120.Therefore the control signal, sending based on total current can be limited to the control signal that impels electric drive motor 62 to slow down during higher than threshold value in total current.In some cases, total current can comprise the electric current being drawn by blade CD-ROM drive motor 110 and electric drive motor 62.Although total current can also comprise the electric current being drawn by peripheral equipment (such as gauge, telltale, lamp etc.), consider the relative scale of related value, roughly can ignore the contribution of peripheral equipment to total current.Therefore, in the time that total current exceedes threshold value, this event can represent owing to running into obstacle, thick grass, wet grass or other need to, for blade motor 110 provides extra current, cause blade motor 110 drawing heavy current, to attempt to keep the rotative speed of blade motor 110.For realizing the best of battery powered riding lawn Hospital trolley for nursing 10 or cutting property equably, reduce actuating speed and may expect.Therefore,, when running into thick grass or wet when careless, can reduce actuating speed total current is remained in the scope being limited by driving governor 150 and to realize the improvement of cutting property.Similarly, battery powered riding lawn Hospital trolley for nursing 10 runs in the embodiment of abrupt slope or obstacle therein, and electric drive motor 62 can draw the electric current of increase to attempt keeping speed in the time crossing abrupt slope or obstacle.If the total current of drawing exceedes threshold value, driving governor 150 can reduce actuating speed the load on electric drive motor 62 is reduced to the level of expectation, thereby maximizes or raising battery life.
Therefore,, by monitoring total current, controlling actuating speed when improving cutting property and/or to improve battery performance, driving governor 150 can cause affecting any or both situations in electric drive motor 62 and blade CD-ROM drive motor 110.In some embodiments, driving governor 150 can automatically insert control signal with based on total current control actuating speed (for example,, by electric drive motor 62 is slowed down).In this respect, in the time that total current exceedes threshold value, driving governor 150 can automatically make electric drive motor 62 slow down.In other embodiments, in the time that total current exceedes threshold value, except only providing input to reduce actuating speed, driving governor 150 can also be configured to the operation of the total current control electric drive motor 62 based on received.For example, driving governor 150 can be configured to limit the respective range of specific speed control inputs for total current.In this respect, can determine the optimum performance characteristic of speed control inputs with the respective range corresponding to for total current value based on test figures.For example, based on test figures, can limit optimization or improve cutting property and/or the speed of battery life for the speed control inputs of each corresponding total current scope.
